San Mateo -- San Mateo County will open a homeless shelter at a National Guard Armory in San Mateo on Monday, despite having to pay higher rent.

The San Mateo County Housing Division had been negotiating with the National Guard, which recently got approval to raise nightly rent for the facility from about $290 to $450.

The county had petitioned for a lower rent, but Pat West, director of the county's housing division, said the county dropped its objections so it could set up the winter shelter at the facility on Humboldt Street.

The shelter, which can accommodate 90 people, will be open until March.
